IMPROVED ROLLING-.PIN AND DOCKER FOR BISCLHT.

Specification forming part ofv Letters Patent No'. 33,@33, dated August 13, i861.

T0 all whom t may concern:

Be it 'known that I, ADAM EXTON, of the city of Trenton, in the county of Mercer and State of New Jersey, have invented a new and useful Improvement in RollingIins and Dockers for Rolling,])oeking, Stamping, and Finishing Crackers, Biscuit, ttc.; and I do hereby declare that the followingl is a full, clear, and exact description of the construction and operation of the saine, reference being had to the annexed drawingsunaking a part of this specification, in which- Figure lis a perspective view; Fig. 2, a vertical transverse section taken through the middle of the decker, and Fig. 3 a vertical transverse section through the middle of one of the guides C D in l.

The same letters of reference in each ofthe respective figures indicate similar parts of the construction.

Thus A B represent the board or table on which the operation of rrlling and docking the crackers or biscuit is to be performed, and C D the guides or rails fastened on each end of the said board or table.

E F G H represents the shaft or extremities of the rolling-pin, and I J M the roller and decker attached to the middle thereof. The two small wheels E Fon each end of the shaft of therolling-pin have the middle part or wheel F, which rolls on and over the guides C D, reduced in diameter, so that the edges thereof form two flanges or projections, whereby to embrace the guides C D, and thus retain the rolling-pin in its proper position over and on the board or table. rlhis'reduced part of said wheels F F should each be of the same diameter, so as to cause said rolling-pin to move parallel over the board.

N C represent a concave depression or groove across the upper surface of the board. This groove is for the purpose of forming the under side of the cracker or biscuit into any particular shape that may be desired by the manufacturer.

I J show the roller, and M the docking points, pricks, or nibs, with the stamp or letters of makers name attached thereon and forming a part of said roller. The roller I J is constructed in a peculiar manner and of a special form, viz: It is not concentric with shaft E F G H, but is eccentric therewith, and

the docking points, pricks,ornibs are so placed on the surface of the eccentric roller I Jthat the face of the cracker or biscuit cannot be blistered or torn up during the process of docking K represents the tail piece or stop of the roller-pin, (shown in section, Fig. 2,) connected therewith, and is intended to check or stop the motion of said roller When it has moved or rolled the required distance over the board and the crackers or biscuit laid thereon.

The operation of my improved rolling-pin and doeker is as follows: The guides or rails C D are made of such a height above the surface of the concave or groove NJC that when the rolling-pin is placed thereon, as shown in Fig. l, the space betweenthe lower sid-e of the roller I J and the 'concave shall equal the intended thickness of the crackers or biscuit to be rolled, docked, and stamped. The pieces or balls of dough to be operated upon are placed in the concave in front of the roller I J, the operator then placing his hands on the shaft of the rolling-pin G and II and then pressing and pushing the same along. It is thus made to roll along the guides C D and on and over the pieces or balls of dough until the tail or stop K is brought overand into contact with the opposite end of the concave or groove, as illustrated in Fig. 2. In this iigure L represents a section of the dough or cracker after the rolling-pin and decker I J M have passed over it and the tail or stop K has been brought into contact with the said concave N C. In order to prevent t-he rollingpin and decker 'from slipping on the guides C D during the operation, as aforesaid, Ipropose to cover said guides with a toothed rack or series of small cogs and to make the smaller wheel F, which runs or rolls on said guides with similar cogs or teeth, to tit and play into said rack, as shown in the transverse section, Fig. 3.

In the drawings, Fig. l, I have shown only one roller and decker IJ M placed on the axle or shaft G H. I wish it to be understood,

however, that I do not limit myself in that respeet, as it will readily be perceived that tWo or more of these rollers and dockers, With the corresponding coneaves or grooves N O, may be attached and formed on said shaft and board, if required; nor do I Wish to confine myself to the use of pricks or points, as above shown, in the process of docking; but prefer tofuse for certain kind ot' work rollers constructed as shown in Fig. 5, whereon the rolling and impressing surface of the roller is channeled or serrated somewhat like the threads ot a screw, with the name inserted therein, as shown in the figure. 'lhe impression formed by this roller on the upper su rface of the cracker or biscuit would be a parallel row of channels, gutters, or grooves across the same, with the maker-S name thereon, as in the former case above mentioned.

I do not claim any of the above-described parts or devices separately considered; but

What I claim as my invention, and desire to secure by Letters Patenhis- The eccentric roller I J in its connection Witnesses:
